X-750

At 50 % load and 230 V input his unit achieves a remarkable 92 % efficiency and boasts Sea Sonic’s patented Hybrid Silent Fan Control. The unsurpassed cooling system combined with a sophisticated fan control is designed to find the optimal balance between silent operations and ventilation. Multi GPU support combined with easily installed fully modular cables further enhance the notable features of this 80 PLUS® Gold certified ATX power supply. All users will be delighted to know that this X-series represents the Green PC technology that helps computer users save on their electricity bill.

80 PLUS®Gold

Seasonic was the forerunner of creating the very first 80 PLUS® Gold certified power supply on the market and since that time it has built a very popular Gold series lineup that covers a full power range of power supplies with impeccable performance and efficiency. The highly efficient 80 PLUS® Gold certification guarantees greater than 87 %, 90 % and 87 % efficiency at 20 %, 50 % and 100 % operating loads, respectively. The clear advantage of buying a power supply with 80 PLUS® Gold rating is the fact that the less energy gets wasted during power conversion, the lower the operating costs will be for the user.

Benefits of this design

Reduced noise without increase in temperature;

Extended fan life due to the reduced number of fan rotations;

Optimized heat dissipation at all times;

Unsurpassed silent performance in Fanless Mode.

Additionally, there is a switch at the back of the power supply which allows users to customize their cooling needs by selecting between the Seasonic S2FC (fan control without Fanless Mode) and the S3FC (fan control including Fanless Mode).

DC to DC Converter Design

The step down DC to DC converter design allows the power supply to be able to serve system components with various voltage needs. Not only is it a flexible, clean voltage conversion solution but it also maximizes the 12 V DC rail output, delivers superior dynamic response and , ultimately, provides for greater system stability.

Sanyo Denki Fan

The world-renowned Sanyo Denki ball bearing fans are made of the highest quality components to ensure ultra-low noise performance. The fan’s perfect balance and even rotations are achieved via the use of spoon-shaped, high-density plastic fan blades that are finished off with smoothed leading edges. Sanyo Denki fans are known for their strict tolerance ball bearings and precision copper axels. Instead of the industry standard of two balancing points they use three points to strengthen the mount and further stabilize the blade.

Tight Voltage Regulation (3 %)

Note: Since the beginning of 2015, Seasonic has implemented changes in its retail box design and modular cables are now packed in a black cardboard box.

“Seasonic has once again taken a Great power supply and made it even better. The enhancements made to the X-Series 650/750/850W power supplies translate to excellent performance, high efficiency and the ability to operate in silent-fanless mode at lower power levels. Throw in a 7-year warranty, a good assortment of all modular cables, really tight voltage regulation, clean DC outputs and you have one very good power supply!
